Solar controller is called solar charge and discharge controller, is used in solar power system, by control of multi-channel solar array to charge for the battery and battery to the solar inverter load power supply automatic control equipment.The solar controller roles are briefly as follows:1. power adjustment function.2. communication function.① simple instructions function;② protocol communication functions, such as RS485 Ethernet, wireless and other forms of background management;3. the perfect protection: electrical protection reverse, short circuit, over flow and so on.

MPPT controller can detect the generation voltage of the solar panel in time and track the maximum voltage and current (VI), allowing the system to charge the battery with maximum power output. Used in solar photovoltaic systems, coordinate solar panels, batteries, load work, is the brain of the photovoltaic system.MPPT is the abbreviation of Maximum Power Point Tracking (MPPT)The system can make photovoltaic panel output more electric energy by adjusting the working state of the electrical module so that the direct current generated by the solar panel can be effectively stored in the battery, which can effectively solve life and industrial electricity of the remote area and tourism area which the conventional power grid can not cover, it does not produce environmental pollution. The outpu...

1. connect the battery. Before connecting the battery, make sure that the battery voltage is higher than 6V to start the controller. If the system is 24V, must ensure that the battery voltage of not less than 18V. The system voltage selection is only recognized automatically when the controller is started for the first time. When installing insurance, pay attention to the safety device from the battery is the maximum distance of 150mm, after confirmed the wiring is correct then switch on the insurance.2. rated voltage, the controller supply load according to the battery voltage . Connect the positive and negative of the loads to the load terminals of the controller, be careful and serious when connect the wire to avoid short circuit. There should connect a insurance device in the loa...
